Not prevalent, but some things are more likely to happen when there's money floating around. A lot of it. Not at a party, but a VC, for example, told me nonchalantly that I could easily take home a woman from the place we were at, assuming I was willing to spend about $3K. This was in the presence of his wife. I hadn't solicited any of this "wisdom", of course.

A friend of mine in tech has been invited to "edgy parties" on two continents and she never went, having heard what they entailed. She had already dealt with plain harassment at work and didn't want to end up in even messier situations outside. There were a couple of famous names that scared her, based on their reputation in her circles.

I'm not sure if this is correlated more to the tech industry, Bay Area customs or a combination. Another friend, who's not in tech, years ago went to what her new boyfriend described as an edgy party, but turned out to be an orgy. One of the women she saw there ended up, by chance, as her fitness instructor years later.

Last but not least, do not assume that people can't be entirely different outside of work. Perhaps because of their intense daytime jobs, some might resort to "activities" as a way to handle stress levels. That said, I can think of at least one person in tech fired for having sex in the workplace.
